They may be a great replacement starter, but look flimsy to me. Other than weight I like the old one. Do they still make new ones in left hand of old model?

They still make the Delco 42MT left handed , a Delco 42MT will set you back 800 bucks new, the MT 39 is a more forgiving starter and draws a lot less amps than the old direct drive starters.I didn't care much for the 39 when it 1st hit the market now it is love  :D

All done.

You guys are amazing. After studying the clock/rotate setup and looking at the wiring and fitment again, it was clocked one place. Fit perfectly fine. When it was touching, it appears that if that bolt was not there it would clear. Wrong, still was too tight. One mod I did was to add some wire and wire nuts on the solenoid for easier and faster remove/install in the future.

Now, all you need to do is remove the two main power cables, the two wire nuts, and the three mounting bolts. Literally a ten minute job.

Thanks again BCM busnuts!

Clifford, I had the same thought but did not have the right auto connectors handy. Just moved and it was enough of a pain having to hunt for tools in three different places and make multiple trips fetching all the unanticipated ones like the torx bolts to change the mount.

Figure if I get too much shiiitte here, it is a very simple to swap and super accessible. Could also just put some shrink tubing and seal them up too. Or just leave them alone. Lol

butt connectors are for never removing...
if you don't own a pair of   Thomas & Betts crimper pliers or better...u should use wire nuts... :)
